To evaluate recent milled rice quality of the super hybrid rice in China, ten grain quality traits and their superior quality rates of 49 super rice hybrids have been analyzed. The results showed that the average superior quality rates of the ten grain traits of the tested super rice hybrids were 81.4%, ranging from 34.7% to 100%. Among which, the brown rice rate, milled rice rate, head milled rice rate, gelatinization temperature, gel consistency and brown rice protein content had higher superior quality rates(>89%). The super hybrids derived from the male sterile lines Guangzhan 63S, Tianfeng A or Peiai 64S had lower chalky grain percent, chalkiness degree and amylose content, as well as softer gel consistency. In general, the twoline super hybrids showed lower chalky grain percent, chalkiness degree and amylose content, as compared with the threeline super hybrids. It was noticed that the tested super rice hybrids showed not only higher chalky grain percent(44.9%) and chalkiness degree(9.7%), but also lower superior quality rates(34.7% and 51.0%). The emphasis of improving rice quality for super hybrid rice was discussed.
